it feels like every time i take amoxicillin that it makes my prilosec not work, and if it is not working then i cant sleep or anything.. In some worse cases it makes me throw up because of how bad it gets.. I have been taking 40mg everyday for the past 3 years and it really works good until i take an antibiotic.. If i miss a day it usually doesnt bother me because of how long i have been taking it but it i dont take it its really bad.. I have gone thru at least 2 gallons of milk a night when i have to take antibiotics, so if you could help me out i would be greatly appreciated..
